Questions
- Two 60.0Ωresistors are connected in parallel and this parallel arrangement is then connected in series with a
30.0Ωresistor. The combination is placed across a 120. V potential difference.
(a) Draw a diagram of the circuit.
(b) What is the equivalent resistance of the parallel portion of the circuit?
(c) What is the equivalent resistance for the entire circuit?
(d) What is the total current in the circuit?
(e) What is the voltage drop across the 30.0Ωresistor?
(f) What is the voltage drop across the parallel portion of the circuit?
(g) What is the current through each resistor? - Three 15.0 Ohm resistors are connected in parallel and the combination is then connected in series with a 10.0
Ohm resistor. The entire combination is then placed across a 45.0 V potential difference. Find the equivalent
resistance for the entire circuit.
