When you switch a voltmeter from a lower to a higher voltage range, an additional resistor is added in series with the meter, increasing the voltage necessary to create the same voltage drop across or current flow through the actual meter movement.
current through the switch become 0.and switch become a high value resistor.
current through the switch become 0.and switch become a high value resistor.
It's the product of the resistance of that resistive load and the current passing through it.
Such a circuit either has no voltage source, or some part of the circuit is open, e.g., an open switch.
Closing a switch in an electrical circuit will complete the circuit. The supply voltage will then be applied to that circuit, and current will flow through that circuit.
The current flows through the cable of the plug, to whatever wants to be turned on.
When the light switch is turned on and a light bulb is connected in the circuit a current will flow through the circuit. Likewise when the switch is opened, the current will stop flowing in the circuit.
it is a switch,current goes through when switch is on and the current doesn't go through when its off you're welcome
If the switch is open, current does not flow.
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
