Question

When a 20.V emf is placed across two resistors in series, a current of 1.0A is present in each of the resistors. When the same emf is placed across the same two resistors in parallel, the current through the emf is 5.0A. Find the magnitude of the two resistances.

Name: when a 20v emf is placed across two resistors in series a current of 10a is present in each of the resistors when the same emf is placed across the same two resistors in parallel the current through t

Step 1

Calculate the current in each resistor: Current in resistor 1: I = 20.V / R1 = 1.0A Current in resistor 2: I = 20.V / R2 = 0.5A Show more…
