Question

if the voltage across the terminal of circuit is 20V and the resistor connected is 10 ohms. The calue of the current flowing in the circuit is?

Answer 1

Answer:

hi

Explanation:

Assuming you mean that the 20 volt cell is placed across the resistor combination, the series combination is 30 ohms. That means that 20/30, or 0.66666… amps flows through both resistors. the current in the 10 ohm resistor is the same as the current in the 20 ohm resistor (because they are connected in series). What is different about them is the voltage drop. The 10 ohm resistor will drop 6.666… volts, while the 20 ohm resistor will drop 13.33333… volts

If the cell is not connected across the resistors, then the current in the 10 ohm resistor will be zero.
