Numericals on poteential and potential difference

1.what is potential when 10 joules of work done in moving 10 coloumbs of charge?
2.what is potential when 50 joules of work is done in moving 10 to power of 19 electrons?
3.how much work must be done to move 10 to power 19 electron across a potential difference of 220v?
4.find amount of potential at point point b if 10 v of potential is at point a which does a work of 20 j in moving 5 c of charge?
5.what is difference between potential difference and emf?
6.how can u convert galvanometer to voltmetre.why volt metre always conected in parrale?
7.what is the fifference beyween voltmetre and volta-metre?
8.define one volt?
9.what are sources of potential in a circuit?
10.how much charge flows across a pd of 220v when 11j of work is done in moving a charge?
11.find potential when 20 j of work done in moving 5 amp of current flows for 2 seconds ?
12.find potential when 1.6 joules of work done in moving 10 power of 19 electrons ?
