Current flowing in a circuit depends on two variables. identify these variables and their relationship to current. a) current is proportionate to the conductance of the circuit and precisely proportional to the voltage applied across the circuit. b) current is conversely proportional to the electrical tension of the circuit and corresponds to the resistance across the circuit. c) current is inversely proportional to the resistance of the circuit and directly proportional to the voltage applied across the circuit. d) current is commensurate to the resistance of the circuit and directly proportional to the electric pressure applied across the circuit.

C) Current is inversely proportional to the resistance of the circuit and directly proportional to the voltage applied across the circuit.

Explanation:

Ohm's law states that current is directly proportional to the potential difference across the circuit i.e. voltage.

I ∝ V

⇒ V = I R

where R is the resistance.

Current also depends on resistance offered by the circuit.

So, more the potential difference, more the current but more the resistance offered by the circuit, lesser current would flow.

Current is inversely proportional to the resistance and directly proportional to the voltage across the circuit. Voltage is provided by a cell or a battery. Resistance is offered by the wire and the components connected in the circuit. Sometimes the batteries also have internal resistance which adds up.
