The load will be zero after the switch is turned off. if power is still being drawn then the switch is quite likely faulty

Is 160 ohms reading on a switch bad?
For a switch the reading should be in the zero ohm range. Corrosion or pitted contacts will start to raise the resistance rating on a switch. This size of rating on the switch will start to raise the temperature of the switch because the switch starts to act like a load in the circuit.
Feed drops to zero volts when light switch is turned on back to 120 volts when turned off feeds fluorescent lights?
voltage is measured by voltagd drops. When a switch is open/ off there is a voltage difference between one side to the other. when the switch is on there is no drop from one side of the switch to the other. That is normal operation. If switch is on, and you get a voltage reading across the switch, the switch is bad.
What is a free wheeling diode how is it connected in an automatic voltage regulator circuit?
Inductive load will accumulate stored energy. If an attempt is made to open the switch this energy will arc across the contacts of the switch, and could cause damage to the circuit components. Freewheeling diodes are placed across inductive loads to provide a path for the release of energy stored in the load when the load voltage drops to zero.
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.
How much will neutral current be in a 3phase 4-wire y system with a balanced load?
Balanced load means no unbalanced currents, so the neutral current should be near zero.
When measuring voltage the unit power should be turned off or on?
With the power turned off the voltages in the unit should be zero so no information would be gathered, excect that it it isn't zero there's a serious fault. The power should stay off until the voltmeter is connected, and then the operator should step back and turn the power on using one hand only.
What is zero current transformer?
It is a transformer with No load attach to it.
When voltage regulation will be zero it operate it?
A transformer will operate with a voltage regulation of zero when it is not supplying a load.
What you will do if both feed pumps tripped when boiler is in service?
Immediately the load on Generator should be reduced to Zero n desynchronised, and the turbine be tripped.
Will an open switch record a resistance of zero ohms?
no...... ideal open switch should have a resistance of infinity... the question should be a closed switch http://wiki.answers.com/Q/Will_an_open_switch_record_a_resistance_of_zero_ohms" but this is also false because any good conductor will have a small resistance the connecting wire resistance is exhibitted across the terminals of the switch
What is zero voltage regulation in transformers and what it means?
'Zero voltage regulation' indicates that there is no difference between its 'no-load voltage' and its 'full-load voltage' -this is only the case for an 'ideal' transformer.
Why do the load extension graph passes through the origin?
This shows that when suspended load is zero. the extension in wire is also zero which is correct. For more details, contact at saqibahmad81@yahoo.com
