Whiteboard Investigation

This circuit consists of an ideal battery and five resistors as shown.


R1, R2 and R4 are 20.0 W

R3 and R5 are both 10.0 W

V1 provides 10.0 VDC.

Q1: Draw a simplified circuit with only series circuit elements.

Q2: Draw a simplified circuit with only ONE series resistor

Q3: Find the total equivalent resistance for all resistors in this circuit.

Q4: What current flows through the battery?

Q5: What current flows through each resistor?

Q6: What is the potential difference (voltage drop) across each resistor?
