Question

complete the table below based on one's law​

Answer 1

Answer:

Formulas:-

According to ohms law

$\sf v\propto I$

$\\ \sf{:}\longrightarrow \dfrac{V}{I}=constant=R$

SOLUTION:-1

Here

• Voltage(v)=20v
• Resistance (R)=5ohm

$\\ \sf{:}\longrightarrow \dfrac{V}{I}=R$

$\\ \sf{:}\longrightarrow I=\dfrac{V}{R}$

$\\ \sf{:}\longrightarrow I=\dfrac{20}{5}$

$\\ \bf{:}\longrightarrow Current_{(I)}=4A$

SOLUTION:-2

Here

• Current (I)=8A
• Resistance (R)=2ohm

$\\ \sf{:}\longrightarrow V=IR$

$\\ \sf{:}\longrightarrow V=8\times 2$

$\\ \bf{:}\longrightarrow Voltage_{(V)}=16v$

SOLUTION:-3

Here

• Voltage (v)=12v
• Current (I)=3A

$\\ \sf{:}\longrightarrow \dfrac{V}{I}=R$

$\\ \sf{:}\longrightarrow R=\dfrac{12}{3}$

$\\ \bf{:}\longrightarrow Resistance_{(R)}=4ohm$

$\boxed{\begin{array}{c|c|c}\boxed{\sf V} &\boxed{\sf I} &\boxed{\sf R} \\ \rm 20 &\rm 4 &\rm 5 \\&&\\ \rm 16 &\rm 8 &\rm 2 \\&&\\ \rm 12 &\rm 3 &\rm 4\end{array}}$
