Question

10)

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.

Answer 1

The current is “inversely proportional to resistance of circuit” and “directly proportional to voltage across the circuit”.

Answer: Option C

Explanation:

The amount of current flowing through the circuit depends upon the resistance and voltage.

Current depends on resistance of the circuit. If there is high potential difference, the current in circuit will be high. The high resistance leads to less current.

Mathematically the relationship between voltage, current, and resistance is given as
`V=I * R`. This is also stated as Ohms law.
