How do you calculate battery

SERIES CONNECTION OF BATTERY

E=e.m.f of one cell, volt

n=Number of cell.

r=Internal resistance of one cell, ohms

Total e.m.f (E_T)= n*E, volt

Total internal resistance (R_T) = n*r ,ohms

Total current (I)= nE/nr+R , ampere

PARALLEL CONNECTION OF BATTERY

E=e.m.f of one cell, volt

n=Number of cell.

r=Internal resistance of one cell, ohms

Total e.m.f (E_T)=E , volt

Total internal resistance (R_T)=r/n ,ohms

Total current (I)=nE/r+nR

CAPACITY OF A BATTERY

Capacity =Ampere * Hours .

SOME OTHER IMPORTANT TOPIC OF BATTERY

Battery is series connection

1)e.m.f increase.

2)Ampere is constant.

Battery is parallel connection

1)e.m.f constant.

2)Ampere is increase.

THE CAPACITY TYPES OF A BATTERY

Two types of battery capacity

1)Ampere hour efficiency .

2)Watt hour efficiency.

1)AMPERE HOUR EFFICIENCY

Discharging ampere hour /Charging ampere hour × 100

# Lead acid cell = 90% to 95%.

2)WATT HOUR EFFICIENCY

Discharging watt hour/Charging watt hour × 100.

# Lead acid cell = 80% to 85%.

What is a battery

CELL AND BATTERY BATTERY Battery Battery is chemical energy convert to electrical energy. TYPES OF CELL Cell is two types------- 1)Primary cell 2)Secondary cell 1)PRIMARY CELL A cell which convert chemical energy to electrical energy.It is active few hours and then stop working. Primary cell is not rechargeable. TYPES OF PRIMARY CELL 1)Voltaic cell 2)Daniel cell 3)Leclanche cell 4)Silver oxide cell 5)Dry cell 6)Mercury cell 1)VOLTAIC CELL A) Pot--Glass jar. B) Anode--Copper. C) Cathode--Zinc. D) Electrolyte - H 2 SO 4. E) E.M.F--1.08 volt per cell. USED OF VOLTAIC CELL Present day this is not used. 2) DANIEL CELL A) Pot-- Copper. B) Anode--Copper.

What is series resonance circuit

RESONANCE CIRCUIT CONDITION OF RESONANCE Must be have two components which is storage energy form of magnetic field and electric field. Inductor is energy storage device which is energy store form of magnetic field. Capacitor is a energy storage device which is energy store form of electric field. Resistive circuit is source voltage and source current same phase. Power factor must be unity. X L =X C RESONANCE FREQUENCY F r =1/2 ∏ √L.C TYPES OF RESONANCE CIRCUIT 1)Series resonance circuit. 2)Parallel resonance circuit. SERIES RESONANCE CIRCUIT Series resonance circuit Inductor, Capacitor, and Resistor are connected series line, its called series resonance circuit. IMPORTANT TOPIC OF SERIES RESONANCE CIRCUIT Series resonance circuit have minimum impedance. Series resonance circuit have maximum current. V L =V C at resonance frequency. X L =X C at resonance frequency. In the circuit is maximum current. In the ci

What is parallel resonance circuit

PARALLEL RESONANCE CIRCUIT Parallel resonance circuit Inductor, Capacitor, and Resistor connected are parallel line its called parallel resonance circuit. RESONANCE FREQUENCY OF PARALLEL RESONANCE CIRCUIT F r =1/2 ∏ √L.C POWER FACTOR Power factor is unity of parallel resonance circuit. IMPORTANT TOPIC OF PARALLEL RESONANCE CIRCUIT Parallel resonance circuit have maximum impedance. Parallel resonance circuit have minimum current. The circuit types is capacitive after resonance frequency. The circuit types is inductive before of resonance frequency. I C =I L at resonance frequency. The circuit types is resistive at resonance frequency. Power factor is leading after resonance frequency. Power factor is unity at resonance frequency. Power factor is lagging before resonance frequency. Net total resistive current is zero. Voltage and current in phase. The amount of circuit current ot depend on the impedance. QUALITY FACTOR IS PARALLEL RESONANCE CIRCUIT Q=I C or I L /I NO
