4. Figure 20-31 depicts a household circuit containing several appliances and a circuit breaker attached to a 120 V source of potential difference. a. Is the current in the toaster equal to the current in the microwave? b. Is the potential difference across the microwave equal to the potential difference across the popcorn popper? c. Is the current in the circuit breaker equal to the current in all of the appliances combined? Toaster: 16.9 0 W Microwave: 8.0 0 Popcorn popper: 10.0 0 Circuit breaker: 0.01 0 11 O- O 120 V Figure 20-31 5. Determine the equivalent resistance for the household circuit shown in Figure 20-31. 6. Determine how much current is in the toaster in the household circuit shown in Figure 20-31. 7. Physics in Action A certain strand of miniature lights contains 35 bulbs wired in series, with each bulb having a resistance of 15 9. What is the equivalent resistance when three such strands are connected in parallel across a potential difference of 120.0 V
