Mixed Circuit Math problem Solved in Bangla | Electrical Engineering Bd

A lot of circuit combination made with mixed circuit .when we findout the carrent .voltage,ampere then we do transfar to series circuit.so from it, we can get equivelent resistans.then do the different loop findout and calculate all in Resistor or load. In this total operation we use of the most ohms law .This laws have three conditon of series and parallel .
Conditon of series;
1.I total=i1=i2=i3=..
2.V total=v1+v2+v3..
3.Req=r1+r2+r3...
Condition of parallel;
1.I total=i1+i2+i3...
2.V total=v1=v2=v3...
3.1/Req=1/r1+1/r2+1/r3.....
