Question

find v? I = 10A ,R=20K ohm
find R? I= 15 mA , V =30v
find R ?I = 20A , V = 50 kv
(V is voltage , I is current , R is resistance , k is kilo , m is milli)

it's urgent​

Answer 1

FINAL ANSWER:

i  V=200kV

ii  R=133.33 Ω

iii R=2500Ω

GIVEN:

i  I = 10A ,R=20K ohm

ii  I= 15 mA , V =30v

iii I = 20A , V = 50 kv

TO FIND:

i find v?

ii find R?

iii find R ?

FORMULA USED:

V=I×R

HERE

V = VOLT (V)

I = CURRENT (A)

R = RESTANCE (Ω)

SOLUTION:

i V=I×R                                                  (1kV=1000V)

  V=10×20000

   V=200000 V

            or

       V=200kV

ii V=I×R                                                 (1mA=0.015A)

   30=0.225V=I×R              

      R=$\frac{30}{0.225}$

      R=133.33 Ω

iii  V=I×R                                              (1kV=1000V)

     50000=20×R      

      R=$\frac{50000}{20}$

      R=2500Ω
