- When working with high-power electric circuits, it is advised that whenever possible, you work "one-handed” or “keep one hand in your pocket." Why is this a sensible suggestion?arrow_forwardRefer to Figure 10.17 and the discussion of lights dimming when a heavy appliance comes on. (a) Given the voltage source is 120 V, the wire resistance is 0.800 and the bulb is nominally 75.0 W, what power will the bulb dissipate if a total of 15.0 A passes through the wires when the motor comes on? Assume negligible change in bulb resistance, (b) What power is consumed by the motor?arrow_forwardSuppose that by mistake you leave ten 50-W light bulbs turned on at your house for 24 hr. Say that the cost of electricity is 6 cents per kW · hr. (i)How many Joules are used by the ten light bulbs over the 24 hours? (ii) calculate the cost for this mistake?arrow_forward
