Determine the voltage drop (from top to bottom) across the 16 ohm resistor in the circuit shown. Determine the voltage drop across the 4 ohm resistor. What is the voltage V?
1) Since 16Ohm and 8Ohm are series, according to Ohm's law, the voltage drop on 16Ohm is
2) Similarly, the voltage drop on 4Ohm is 12*(4/(4+8))=4V
3) We ...
This complete solution includes calculations, answers and a brief explanation of voltage drop in the resistor. It uses the concepts of Ohm's Law and electric potential.
