Question

Three 7 0hm resistors are connected in series across a 10 V battery. What is the equivalent resistance of the circuit?

Answer 1

Given

Three 7 ohm resistor are in series.

The battery is V=10V

To find

The equivalent resistance

Explanation

When the resistance are in series then the resistance are added to find its equivalent.

Thus the equivalent resistance is:

$R=7+7+7=21\Omega$

Conclusion

The equivalent resistance is 21 ohm
