What else can I help you with?
Why making rating as the current flowing immediately before the switch is closed must be zero?
Rephrase your question so that it makes sense! <<>> The current through the switch before being closed is zero. The current in the circuit does not start flowing until the circuit's switch is closed.
What does the reading on a ammeter say when the switch is open?
An open switch in a circuit will stop all current flow so the ammeter should read zero amps.
Soft switching in power electronics?
It is to open the power-switch at zero current to minimize the looses during switching.
What is the value of current at zero volts?
Zero volts produces zero current.
What is mean by Zero Voltage Switching?
turn on and turn off a device and act as a switch is called as zvs
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 the current of zero watts bulb?
zero
How do you zero phase current tranformer test?
How do you zero phase current transformer test
How much current flows through a resistor with zero potential difference?
No current flows when the the voltage is zero.
How does a switch control an electric device?
A switch basically represents a gap in the electric circuit. Electric current can pass through a circuit only if it is complete. An incomplete circuit can never pass a current through it. When the switch is in the 'off' position, the circuit has a break (gap) in it. When you put the switch in 'on' position, the circuit wire join and the circuit gets completed.
The range switch on a millimeter is set on 300 milliamps How much current is the meter indicating if the needle is pointing to 1.85 on a scale of zero to three?
185 milliamps.
When a switch is turned off should the load be zero?
The load will be zero after the switch is turned off. if power is still being drawn then the switch is quite likely faulty
