Answer:

9.9 volts is the correct answer ...

Explanation:

Current= 3A (given)

Equivalent resistance= 3.3 ohm

therefore, V= IR

V= 3*3.3

V=9.9

Hope it helps

as \: 4Ω \: and \: 6Ω \: resistors \: are \: in \: \\ series

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: r = 4Ω + 6Ω

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  r = 10Ω

now \: we \: put \: the \: single\: resistor \: of \: 10Ω

as \: 10Ω \: and \: 5Ω \: resistors \: are \: in \:  \\ parallel

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \frac{1}{r}  =  \frac{1}{10} +  \frac{1}{5}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \frac{1}{r}  =  \frac{1 + 2}{10}

 \\   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: r =  \frac{10}{3} Ω

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  i = 3 \: amphere

potentil \: difference \:  = \pink{ i \times r}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  >  \frac{10}{3}  \times 3 \\

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    \:  \:  \:  \:  \:  \: =  > \:  10 \: volt \\
