In the circuit shown in Figure 20.74, the emf of the battery is 7.9 volts. Resistor R1 has a resistance of 23 ohms, and

resistor R2 has a resistance of 44 ohms. A steady current flows through the circuit.

(a) What is the absolute value of the potential difference across R1?

(b) What is the conventional current through R2?
