Understanding Terminal Voltage

The video tutorial explains the concept of 'tegangan jepit', which is the voltage across the terminals of a power source like a battery after connecting it to an external load. It covers the calculation of this voltage using the total current and resistance in the circuit. The tutorial includes two example problems to illustrate the calculation process, one involving a parallel circuit and the other a Wheatstone bridge configuration.

What is terminal voltage?

• Voltage across the battery when not connected to any load

• Voltage across the external load connected to a battery

• Voltage across the internal resistance of a battery

• Voltage across a short circuit

Which of the following is an example of an external resistance?

• The internal resistance of a battery

• A voltmeter

• A light bulb

• A battery charger

What does EMF stand for in the context of batteries?

• Electromagnetic Field

• Energy Measurement Factor

• Electromotive Force

• Electric Motor Function

How is the terminal voltage calculated in a circuit?

• By adding the EMF to the internal resistance

• By subtracting the internal resistance from the total resistance

• By multiplying the current with the external resistance

• By multiplying the current with the internal resistance
