Answer on Electric Circuits Question for abhay

Question #10943
Subject Physics

Q1. In the verification of Ohm's Law, what is observed when the ratio of potential differences and current (V/I) is calculated for all the readings? What do you conclude?
Q2. The values of current I flowing in a given resistor for the corresponding values fo potential difference V across the resistor are given below:
I (amperes) 0.5 1.0 2.0 2.5 3.0 4.0
V (volts) 0.1 0.2 0.4 0.5 0.6 0.8
Plot a graph between V and I and calculate the resistance of that resistor.
Q3. The potential difference between the terminals of an electric heater is 250 V, when it draws a current of 10 A. What current will the heater draw, if the potential difference is increased to 300 V?
Q4. What will be resistance of a metal wire of length 2 m and area of cross section 1.25×10-6 m2, if the resistively of the metal is 1.6 × 10-8 Ωm ?
