What happens inside a voltmeter when you switch it from a lower to a higher voltage range?
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.
What happens when a switch in a current is opened?
current through the switch become 0.and switch become a high value resistor.
What happens when a switch a current is opened?
current through the switch become 0.and switch become a high value resistor.
What is the voltage across the load R when the switch is ON?
It's the product of the resistance of that resistive load and the current passing through it.
What is a circuit with no current running through it?
Such a circuit either has no voltage source, or some part of the circuit is open, e.g., an open switch.
When a switch in an electrical circuit is turned off what will happen?
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.
What happens when you switch plug sockets on?
The current flows through the cable of the plug, to whatever wants to be turned on.
What is happening when a switch is off?
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.
What is a vibration switch?
it is a switch,current goes through when switch is on and the current doesn't go through when its off you're welcome
What happens if the switch is open?
If the switch is open, current does not flow.
Is BJT is a current control device or voltage control device?
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
What controls the flow of electric current?
EMF force or voltage
