Question

A 6-V battery is temporarily short-circuited. the short-circuit Isc is 30 A. what is the internal resistance

Answer 1

Answer:

example

Explanation:

Internal resistance refers to the opposition to the flow of current offered by the cells and batteries themselves resulting in the generation of heat. Internal resistance is measured in Ohms. ... Example: 1 The potential difference across the cell when no current flows through the circuit is 3 V.

Answer 2

Concept:

• Ohm's law
• Internal resistance
• Short-circuiting
• A short circuit is a type of electrical circuit that has no or very little electrical impedance, allowing current to flow in an undesired direction.
• As a result, the circuit receives an excessive amount of current. An "open circuit," which is a connection between two nodes with an infinite resistance, is the opposite of a short circuit.

Given:

• Voltage V = 6 V
• Current I = 30 A

Find:

• The internal resistance R of the battery

Solution:

According to Ohm's law, the potential difference is the product of current and resistance.

V = I*R

We know that the potential difference is equal to the voltage of the battery which is 6V and the current is 30A.

V = IR

6 = 30 R

R = 6/30 = 1/5

R = 0.2 ohms

The internal resistance is 0.2 ohms.
