What's up? We are going to have fun! This is our first contest for electrical circuits. Solve the problem, submit your answers and cross your fingers to be the lucky winner! Problem Find and :
The mesh analysis used to solve the circuit which has a supermesh. After solving the circuit, power of sources determined.
A DC resistive circuit consisting of one voltage source and one current source and three resistors is solved using source definition, KCL and KVL.
A simple circuit with two voltage sources and two resistors solved using only KVL.
Turning off a source used in solving circuits with the superposition, means setting its value equal to zero. A voltage sources become a short circuit when turned off. To turn off a current source it should be replaced by an open circuit. Dependent sources cannot be turned off.
The ideal independent voltage and current sources are explained. Their symbols and voltage-current characteristics are presented. It is shown how their definitions can be used to solve problems. Some examples are also provided to clarify their characteristics.
Finding power and conductance of resistors from the current and resistance
Finding the power of elements and determining which one is supplying power and which one is absorbing it.
