Question

Given a 20.0 volt battery connected to two 40.0-ohm resistors connected in parallel. What current comes out of the battery in Amperes? 2.00 1.00 0.500 3.00 4.00

Answer 1

Given

The voltage of the battery, V=20.0 V

The resistance of the two resistors are 40 ohm each.

The two resistance are connected in parallel

To find

The current through the circuit.

Step-by-step explanation

The resistors are connected in parallel

Thus the equivalent resistance is

`R=(40*40)/(40+40)=20\text{ ohm}`

By Ohm's law,

`V=RI`

where I is the current through the battery

Putting the values

`\begin{gathered} 20=20I \\ \Rightarrow I=1A \end{gathered}`

Conclusion

The current through the battery is 1.00 A
