Question

Find the following potential differences. The magnitude of the potential difference DeltaV1 across the resistor of resistance R1 = 15.0 Ohm. The magnitude of the potential difference DeltaV2 across the resistor of resistance R2 = 45.0 Ohm. The magnitude of the potential difference DeltaV3 across the resistor of resistance R3 = 20.0 Ohm. The magnitude of the potential difference DeltaV4 across the resistor of resistance R4 = 25.0 Ohm

Find the currents through and the potential difference across each resistor in the circuit shown on the diagram . Use the following values: EMF = 12.0 V, R1 = 15.0 Ohm, R2 = 45.0 Ohm, R3 = 20.0 Ohm, and R4 = 25.0 Ohm.

Answer 1

Without the diagram, or a good description thereof, we cannot help you.

Answer 2

Is this a series circuit?
is it a parallel gircuit?
We need to see the diagram.
