Resistor 1 has a resistance of 10 N and carries a current of 3 A. Resistor 2 has a resistance of
5 and carries a current of 10 A. Which resistor has
the greater potential difference?

Resistance 2.

Explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

Where;

Note: Voltage is the same as potential difference.

Given the following data;

Resistance 1  = 10 Ohms

Current 1 = 3 Amperes

Potential difference 1 = current * resistance

Potential difference 1 = 3 * 10

Potential difference 1 = 30 V

To find the potential difference in 2;

Resistance 2 = 5 Ohms

Current 2 = 10 Amperes

Potential difference 2 = 10 * 5

Potential difference 2 = 50 V

Therefore, Resistance 2 has greater potential difference.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
