Show how this ammeter would be connected to the light bulb circuit to measure the circuit’s electric current: Also, draw a schematic diagram of this same circuit (with the ammeter connected).
Two resistors, 18 ohms and 24 ohms, are to be connected in parallel across the certain voltage source. The power dissipated by the 18-ohm resistor was found to be 72 watts. The parallel resistors are then disconnected, only to be reconnected in a series connection. Across what new voltage source should the series combination be connected to preserve the 72-watt dissipation of the 18-ohm resistor?
Resistors, 10 ohms and 15 ohms, are connected in series. The power being consumed by the 10-ohm resistor is 22.5 watts. Determine the following: the value of the voltage source energizing the circuit; the power being dissipated by the 15-ohm resistor if the two resistors were to be connected in parallel using the same source;

A 1500 W electric heater, 1250 W air conditioner, and a 1000 W microwave oven are plugged into the outlet of a 220 V circuit that has a 20 A circuit breaker. You plug an electric hair dryer into the same outlet. The hair dryer has a power settings of 600 W, 900 W, 1200 W and 1500 W. You start with the hair dryer on the 600 W setting and increases the power setting until the circuit breaker trips. Determine the power setting that will cause the breaker to trip.
You are an electrician on the job. The electrical blueprint shows that eight 500-W lamps are to be installed on the same circuit. The circuit voltage is 277 V and is protected by a 20-A circuit breaker. A continuous-use circuit can be loaded to only 80% of its rating. Is a 20-A circuit large enough to carry this load?
