Question

The current passing through two resistors connected in series is 5A. If these resistors have equal magnitude, each of resistance 2 Ohms, what is the total voltage in the circuit? *Hint: The resistors obey Ohm's law*

Answer 1

Answer:

Explanation:

CURRENT,I=5A

R1=R2=2 OHMS

SINCE R1 AND R2 CONNECTED IN SERIES ,

R NET =R1+R2=2+2=4 OHMS.

WE KNOW ,

V=IR

V=5*4

V=20 VOLTS.

HOPE IT HELPS.

Answer 2

GIVEN:

★Current passing through resistors is 5A. (I)

★The two resistiors are equal in magnitude each equal to 2ohm.

TO FIND:

★The voltage in the circuit. (V)

CONCEPT USED:

★First we will calculate the net resistance.

★We will use Ohm's law to find the voltage .

ANSWER:

For diagram refer to attachment:

Let the two reistors be $R_{1}$ and $R_{2}$

In a series combination,

$\large\green{\boxed{R_{eff}=R_{1}+R_{2}}}$

=>$R_{eff}=(2+2) ohm$

=>$R_{eff}=4ohm$

______________________________________

By Ohm's law,

$\large\purple{\boxed{V = IR}}$

=>$V = IR$

=>$V =5A\times4ohm$

. °. $V =20volt$

Therefore the voltage in the circuit is 20V.

$\large\red{\boxed{Voltage=20V}}$
