Question

find the current through a resistor of resistance R=2 OHM .it the voltage a cross the resistor is 6V​

Answer 1

Answer:

In this case, 2 resistances of 6 ohms and 4 ohms are connected in series. So the total resistance is given as 6+4 = 10 ohms.

The potential difference across the circuit is given as 20 V. The current in the circuit can be determined from the relation I=

R

V

=

10

20

A=2 A.

Hence, the current in the circuit is 2 ampere.

As the current is same across a serially connected circuit, the voltage across the 6 ohms resistor can be determined using the relation: V=IR.

That is, V=2A×6Ω=12 V.

Hence, the potential difference across the 6 ohms resistor is 12 V.
