Solution: The given parameters are, V = 15V R = 3Ω The equation for current using Ohm’s law is, I = V R I = 15 3 = 5A Example 2: The voltage and resistance of a circuit are given as 10V and 4Ω respectively.

WebFrom Ohm’s law, the current running through the circuit is I = V R = 12 V 100 Ω = 0.12 A. 19.49 Thus, the power consumed by the circuit is P = V I = ( 12 V) ( 0.12 A) = 1.4 W. 19.50 Where does this power go? In this circuit, the power goes primarily into … WebElectric current is defined as the rate at which charge flows through a surface (the cross section of a wire, for example). Despite referring to many different things, the word current is often used by itself instead of the longer, more formal "electric current". The adjective "electric" is implied by the context of the situation being described.
