An 80-2 resistor and a 20-2 resistor are connected in parallel, and then this combination is connected in series with a 32-N resistor and a 24-V battery. An ammeter to measure the current through the 80- Q, and voltmeter to measure the potential difference across the 32 Q is needed. 1. Draw the circuit with the meters in place. 2. What is the total resistance of the circuit? 3. What current flows through the 32-2 resistor?
