A battery of is connected in series with resisters of ohm, ohm, ohm, ohm, and ohms. How much current would flow through the ohm resistor?
None of these
Step 1. Given data:
Voltage of battery =
Resistors in series of = = ohms,= ohms,= ohms,= ohms, and = ohms
We have to find the current through the ohm resistor.
Step 2. Formula used:
We know in series combination, the total resistance
Where are resistances in series.
Also, according to Ohm's law, , where voltage, current, resistance,
Step 3. Calculations of current through resistor:
Thus, the net resistance of the circuit is
We know in series combination, the current through each and every resistor is same.
Hence the current through resistor is :
So, the current through resistor is .
Hence, the correct option is option A.
