WebNOTE: When the voltage stays the same, such as in an Automotive Circuit... current goes up as resistance goes down, and current goes down as resistance goes up. Bypassed devices reduce resistance, causing high current. Loose connections increase resistance, causing low current. WebApr 3, 2013 · on 120V: a 120V/120W lightbulb is 120 ohms (when hot) and draws 1 amp. on 240V: a 240V/120w lightbulb is 480 ohms (when hot) and draws 1/2 amp. In both cases, the load is 120 watts but by doubling the voltage, we …
