A _ relationship exists between "current" and "voltage" in terms of the Ohm's law.
Correct answer: C. Linear
- A. Non-linear
- B. Varying
- C. Linear
- D. None of these options are correct
Explanation
According to Ohm's lawV= IRFor a conductor that obeys Ohm's law, a graph of current I as a function of voltage 'V; is a straight line passing through the origin.The slope of the line is tan Ө = I/V = 1/RAs R is constant the slope is constant for ohmic conductors.The I-V graph for ohmic materials is linear.The I-V graph for non-ohmic materials is non-linear (curved).Hence, C is the correct option

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
