In this task, you'll determine how much you use an appliance and calculate the cost of your usage. 0 watts of power requires a voltage of 210. volt b. anode, A special device that prevents excessive current from passing through a circuit is a(n In order to find the greatest power from all the values of appliances (previously found), we need to compare all the values, from P 1 P_1 P 1 to P 5 P_5 P 5 , and see which appliance has the greatest value. The best way to compare the cost of running different appliances is to look at their power consumption, which is measure of how much power they use in Watts. The amount of current in amperes I I I that an appliance uses can be calculated using the formula I = (P R) 1 2 I=\left(\frac{P}{R}\right)^{\frac{1}{2}} I = (R P ) 2 1 , where P P P is the power in watts and R R R is the resistance in ohms.
