Answer to Question #198282 in Mechanics | Relativity for faith

Question

In this circuit, the voltage drop across the upper resistor is 4.5 V. What is the battery voltage? what s the current through the circuit? what is the resistance in the circuit?

The figure shows a rectangular circuit with a battery and two resistors connected in series. The battery is located on the left-hand segment of the circuit, a 30-ohm resistor is located on the upper segment, and a 50-ohm resistor is located on the right-hand segment of the circuit.

Answer 1

(1) Battery Voltage = 4.5 V

(2) Voltage of battery = 4.5 V

Resistance, $R_1=30\space\Omega$

Resistance, $R_2=50\space\Omega$

Total Resistance, $R=R_1+R_2=80\space\Omega$

Total Current in the circuit, $I=\dfrac{V}{R}=\dfrac{4.5}{80}=0.0056\space A$
