Sᴏʟᴛɪᴏɴ A :-

Given:-

• Voltage = 220 V
• Resistance = 1200 Ohm.

To find:-

• Current

------------------

$\longrightarrow \blue { \bold{ Current}} = \frac{ \bold \orange {Voltage}}{ \bold \orange {Resistance} }$

$\longrightarrow \blue { \bold {current}} = \frac{ \bold {220 \: v}}{ \bold {1200 \: ohm}}$

$\longrightarrow \bold \blue{current} = \bold \green{ 0.13 \: amphere}$
