Answer:
The total resistance of a circuit can be found by knowing the potential difference and current flowing through the circuit.
Explanation:
- The connected wires, devices, connected resistors and also the internal resistance of the battery opposes the flow of current through the circuit.
- These combinations gives the total resistance of the circuit.
- In circuits, the total resistance in a circuit can be found from the total resistors connected across the circuit.
- If the potential difference and the current flowing through the circuit is known, then the total resistance in the circuit can be calculated from the Ohms's law.
V = IR
R = V / I
