Sagot :
To determine the source voltage in a parallel circuit, we can use Ohm's Law, which states that the voltage across a resistor is equal to the product of the current flowing through it and its resistance.
Given:
- [tex]\( R2 = 15 \)[/tex] ohms
- [tex]\( I2 = 4 \)[/tex] amperes
We are asked to find the source voltage [tex]\( V_{source} \)[/tex].
Since the voltage across all resistors in a parallel circuit is the same, we can use the given values for [tex]\( R2 \)[/tex] and [tex]\( I2 \)[/tex] to find the source voltage:
[tex]\[ V_{source} = I2 \times R2 \][/tex]
Substituting the given values:
[tex]\[ V_{source} = 4 \, \text{amperes} \, \times \, 15 \, \text{ohms} \][/tex]
[tex]\[ V_{source} = 60 \, \text{volts} \][/tex]
Therefore, the source voltage is 60 volts.
The correct answer is:
B 60 volts
