Answer : -
1) q = +ne
where ,
q = total no.of charges
n = no.of electrons
e = charge of electron
2) V = W / Q
where ,
V = electric potential
W = workdone
Q = charge
3) potential difference = Va - Vb
= W/Q
= W / I× T
4) I = Q × T
where,
I = electric current
Q = charge
T = time
*I = ne / T ( Q = ne )
5) V = IR
where ,
R = resistence
6) P = RA / l
where ,
P = resistivity
A = area of cross section
7) V = V1 + V2 + V3
V1 = IR1
V2 = IR2
V3 = IR3
=> V = IR1 + IR2 + IR3
=> V = I ( R1 + R2 + R3 )
If , V = IRs
=> IRs = I ( R1 + R2 + R3 )
=> Rs = R1 + R2 + R3
8) I = I1 + I2 + I3
ACCOR.TO OHMS LAW,
I = V / R
I1 = V / R1
I2 = V / R2
I3 = V / R3
I = V/R1 + V/R2 + V / R3
I = V ( 1/R1 + 1/R2 + 1/ R3 )
If, Rp = effective resistence
=> I = V/ Rp
V/ Rp = V ( R1 + R2 + R3 )
=>1/Rp = 1/R1 + 1/R2 + 1/R3 ......+ 1/ Rn
9) H = VIT = I^2RT = V^2 T / R
where ,
H= heat
10) E = VIT
where ,
E = electric energy
11) P = W/T
where , P = power
now , putting W = VIT
P = VIT / T
P = VI
Hope this helps you mate ✌✌

Here is ur answer,
(i) Potential difference :work done / charge moved
V = W/Q
SI unit of potential difference is volt
(ii) Current : quality of charge moved/ time taken
I = Q /T
SI unit of current is ampere,
Current is measured by the instrument ammeter .
(iii) Resistance : potential difference/current
R = V/I SI unit of resistance is ohm
(iv)Resistivity =Resistance × Area of cross section / length
p = R× A /L
SI unit is ohm metre
(v) Electric power : work done/time taken
P= W/ T
SI unit is watt
(vi) Electric energy : power× time
E = p×t
SI unit is joule .
