Webtime (t) is measured in seconds (s) One watt is equal to one joule per second (J/s). This means that for every extra joule that is transferred per second, the power increases by one watt. WebPower [ P = V x I ] = 24 x 2 = 48W. Power within an electrical circuit is only present when BOTH voltage and current are present. For example, in an open-circuit condition, voltage is present but there is no current flow I = 0 (zero), therefore V*0 is 0 so the power dissipated within the circuit must also be 0.
