What Is The Voltage Difference And Voltage Drop In Automotive Electrics?
Voltage difference relates to switches in an electrical circuit. When a switch is open, electrical current can only flow from the battery’s positive terminal to the switch. The electricity cannot go any further. The switch side of the circuit is said to possess potential voltage. Or, in other words, has 12 volts at its disposal; the other side of the switch has zero volts available, and so this 12 volts disparity between the two sides of the switch is known as voltage difference. This voltage difference only disappears when the switch is closed and current can flow through the switch. Voltage drop is when current passes through a load, a component that consumes current to power itself such as the headlights. When the 12 volt current is applied to the positive terminal of the component, it has to overcome the component’s inherent resistance. All objects have natural resistance, but many components have designed in resistance to regulate the exact amperage required. When this happens alm
