Meaning of internal resistance
WebInternal Resistance When there is current present in the device or the electrical circuit and there’s a voltage drop in source voltage or source battery is internal resistance. It is caused due to electrolytic material in batteries or other voltage sources. Internal Resistance (r) = … Web· Internal resistance: This is the resistance inside the voltage source or current source of the electric circuit. · Load resistance: When an electric current flows through the circuit, every portion of the circuit (i.e., the connecting wires or any device attached to the circuit) offers resistance to the flow of the current.
