Electric Circuits – Resistors in Parallel
1. You are given 2 different resistors: R1 = 30 Ω, R2 = 15 Ω. You also have access to a 6 V
battery. Please determine the following:
a. the equivalent resistance when all resistors are connected in Parallel;
b. the total current IT for the circuit;
c. the voltage across each of the resistors;
d. the current through each of the resistors.
e. the power dissipated by each resistor, and by the entire circuit.
a) 10 Ω; b) 0.6 A; c) 6 V; d) 0.2 A, 0.4 A; e) 1.2 W, 2.4 W, 3.6 W
2. You are given 3 different resistors: R1 = 300 Ω, R2 = 200 Ω, R3 = 120 Ω. You also have access
to a 12 V battery. Please determine the following:
a. the equivalent resistance when all resistors are connected in Parallel;
b. the total current IT for the circuit;
c. the voltage across each of the three resistors;
d. the current through each of the three resistors.
e. the power dissipated by each resistor, and by the entire circuit.
