Draw a schematic diagram of a circuit consisting of a battery of three cells of each, a resistor, an resistor, a resistor, and a plug key, all connected in series. Also, calculate the value of current through the circuit.
Step 1: Given data
Step 2: Electric Circuit, Battery, Cell, Resistor, plug key, and Series connection:
The total resistance in a series circuit,
Where is the total resistance of the circuit, are the resistance of the resistor connected.
According to Ohm's law,
where is the total resistance in the circuit, is the potential difference across the circuit, and is the total current in the circuit.
The voltage of the battery =
Step 3: Circuit diagram,
Step 4: Current in the circuit:
The total resistance of the circuit,
Where
The voltage across the circuit,
Current in circuit,
Thus, the current through the circuit is .
