Correct option is C
- I = Current
- V = Potential difference (voltage)
- R = Resistance
The mathematical form of Ohm’s law is represented as _______ (Here V = potential difference, I = current flowing through a conductor and R = Resistance.)
Consider a circuit in which three resistors of 10 , 20 and 30 are connected in parallel to each other to a cell of 220 V. The effective resistance and the current in the 20 resistor are _________ and _______, respectively.
The value of resistance gets doubled if its length is _______ (keeping other parameters constant).
The resistivity of a material of length 5 m is 1.6 ×10⁻⁸ ohm–m. If the length of the material is increased by 10 m, then the value of resistivity is __________.
The mathematical form of Ohm’s law is represented as _______ (Here V = potential difference, I = current flowing through a conductor and R = Resistance.)
Two wires, A and B, are made of the same material, but the length of A is 3 times that of B, and the cross-section of A is th of that of B. The resistance of A is:
