To draw: An electrical series circuit with given elements.
To find: The ammeter reading.
Answer to Problem 71A
An electrical series circuit with given elements is shown in Figure 1.
The ammeter reading is 2 A.
Explanation of Solution
Given:
Battery with voltage
Resistance of resistor,
Ammeter to measure current.
Formula used:
According to Ohm’s law, the voltage-current relationship is
Calculation:
Series Circuit:
A circuit in which one or more electrical elements are connected one by one in a chain making a single path is a series circuit.
The current through all the elements is same and the total voltage is distributed to all the elements.
The series circuit for the given element specification is,
Figure 1
The direction of conventional current is from positive to negative terminal outside the battery and negative to positive terminal inside the battery.
The ammeter reading is,
