Question
Download Solution PDFFind the value of V in the circuit shown below.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFKirchoff's Current Law (KCL):
According to the KCL: at any node, the sum of all incoming currents is always equal to the sum of all outgoing currents.\(I_1+I_4=I_2+I_3+I_5\)
Calculation
Consider voltage at point 'a' is V and also take incoming current as negative.
Applying KCL at node A:
\(-I_1+I_2+I_3=0\)
\(-5+{V\over 1}+{V-(-2)\over 1}=0\)
V = 1.5 volts
Additional Information
Kirchoff's Voltage Law (KVL):
According to Kirchhoff's Voltage Law, The voltage around a loop equals the sum of every voltage drop in the same loop for any closed network and equals zero.
\(V=V_{R1}+V_{R2}+V_{R3}\)
\(V=I({R_1}+R_2+R_3)\)
