Question

if the potential in the current is 20 volt and current through the circuit is 20 ampere .calculate the resistence
of current​

Answer 1

Answer:

R=V/I,R=20/20,R=1 Ohm

Answer 2

Given :

Pottential difference ( V ) = 20 V

Current drawn ( I ) = 20 A

Resistance of the curren ( R ) = ?

From ohms law

V = IR

=> V / I = R

=> 20 V / 20 A = R

=> 1 Ω = R

=> R = 1 Ω

Therefore the resistance of the current is 1 Ω.

Extra information :

• Electric current is the amount of charge crossing any crods section of the conductor in 1 second.

• Electric current ( I ) = Q / t

where,

• Q = electric charge
• t = time interval

• Work done ( W) by electric force on positive charge ( q) is called Potential differnce or Voltage

• Potential difference ( V ) = W / q

• SI unit of potential difference is volt.
