2. Adding more resistors in parallel to an existing parallel circuit will:
Increase total resistance
Decrease total resistance
Keep total resistance the same
Increase total current
3. The total resistance in a series circuit is the of individual resistances.
4. In a parallel circuit, the voltage across each resistor is .
5. Consider a series circuit with three resistors: R1 = 10 Ω, R2 = 20 Ω, and R3 = 30 Ω, connected to a 12 V battery. Calculate the total resistance of the circuit.
6. For the same series circuit in question 5, calculate the total current flowing through the circuit.
