What is the energy given off by a 20V bulb which has 10C passing through it?
200J
2J
0.5J
250J
When lighting happen,25 C charge is transferred from could to the ground and 1.25x1010 J energy is produced. Calculate the potential difference within cloud and the ground in unit Volt
4.00 x 108
2.00 x 108
3.00 x 108
5.00 x 108
How must a voltmeter be connected?
In series
In parallel
To a power supply
What is 1 volt equivalent to?
1J/C
1C/J
1A/s
1J/V
Define potential difference
The amount of energy per charge
The amount of charge per energy
The amount of charge per second
The amount of voltage per second
Calculate the potential difference if the work done by 10 coulombs of charge is 50 joules
500 V
5 V
0.5 V
What is the correct equation?
potential difference = charge / time taken
potential difference = work done / charge
potential difference = work done / time taken
potential difference = time taken / charge
work done = energy transferred
true
false
