Question

Help w physics work please

Answer 1

We are given,

• I (current) = 0.4 A
• R (resistance) = 38 ohm

Since, we have to find voltage across 38 ohm resistor we will take R = 38

Similarly, You will have to take the Resistance through which you have to find the voltage...

Now, By ohm' law ;

• Voltage = Current × Resistance
• V = IR

Put the values,

`\sf \: v = 0.4 * 38 \\ \implies \: \sf \: v = 15.2`

Thus, The voltage across the 38 ohm resistor is 15.2 V...
