6 FAQs about [As shown in the figure this is a battery]
How to determine EMF and internal resistance of a battery?
A circuit like the one in the following figure can be used to determine the emf and internal resistance of a battery. The voltmeter in the circuit measures the terminal voltage of the battery. The variable resistor in the circuit allows the resistance of the circuit to be changed.
What is the resistance of a battery if R obeys ohm's law?
Draw a circle around this data point on Figure 1. When R obeys Ohm’s law it has a resistance of 22.2 Ω. (d) One of the circuits A to D shown in Figure 2 was used to obtain the current–voltage data in Figure 1. The maximum resistance of resistor P is twice the resistance of R. The battery has an emf of 14.6 V and negligible internal resistance.
What is a battery?
As we proceed, we will use the term “battery” loosely to refer to a device (such as an electric cell or collection of cells) that can provide a fixed potential difference between two terminals (or electrodes).
What does a battery Arrow mean in a circuit diagram?
We recommend that you always draw a “battery arrow” for each battery in a circuit diagram to indicate the direction in which the electric potential increases and in which direction the conventional current would exit the battery if a simple resistor were connected across the battery.
When a cell is called a battery?
It is only when you have two or more of these cells connected together that you call it a battery. Do not confuse electrical cells with the cells in living organisms. The idea of a circuit diagram is to use circuit symbols instead of drawing each component in the circuit. Always try to make the wires straight lines.
How does the electromotive force of a battery relate to its terminal voltage?
In this explainer, we will learn how to relate the electromotive force (emf) of a battery to its terminal voltage and its internal resistance. Batteries are usually thought of as supplying a potential difference to other components of a circuit in order to produce a current in those components. This is correct.
