SNC1DPower Practice1. If a clock expends 2 W of power from a 1.5 V battery, what amount of current is supplying the clock?[1.34 A]Given:SolutionRequired:Analysis:Final Statement:2. Jessica is using a hair straightener that expends 20kW for 3 days. How much energy did the appliance use?[1440 kW•h]Given:SolutionRequired:Analysis:Final Statement:More Practice:1.How much energy is used by a 40 W bulb left on for 45 seconds?2.A 4 kW heater is operated for 30 seconds. How much energy is released?3.A 2.2 kW heater is left on for a week. How many Joules are expended?4.Assume it takes Usain Bolt 4 seconds to reach his maximum speed (around 10 m/s). If his maximum energy at topspeed is 55 000 J, find his average power in getting to top speed.

Gives

P=2W

V=1.5 V

We know that

"P=IV \\\\I=\\frac{P}{V}"

Put value

"I=\\frac{2}{1.5}=1.3Amp"
