Draw currents in all three branches of the circuit and label a voltage for the 4 ohm resistor for reference i will say that vb is the voltage across the 4 ohm resistor with the same polarity direction as the voltage sources.

What is the voltage across the resistor r. A at what angular frequency is the voltage amplitude across the resistor in anl r c series circuit at maximum value. Express your answer in terms of the variables l c and r. The voltage across the left resistor is 6 volts and the voltage across the right resistor is 6 volts.

Voltage across r 1 ir 1 1ma x 1kw 1v. From the above equation it is clear that for limiting p v must be limited for a particular resistor of resistance r. Voltage across r 3 ir 3 1ma x 6kw 6v.

Where v is the applied voltage across the resistor and r is the resistance value of the resistor in ohms. Ohms law states that the voltage v across a resistor is proportional to the current i where the constant of proportionality is the resistance r. This v is voltage rating of a resistor of power rating p watts and resistance r w.

Ohms law states that vir where v is voltage i is current and r is resistance. In a parallel circuit the voltage drop across each resistor will be the same as the power source. The voltage drop across each resistor with total voltage of 12 v and resistances 5 8 and 2 can be calculated as v 1 12 5 5 8 2 v1 4 v 2 12 8 5 8 2 v2 64 v 3 12 2 5 8 2 v3 16.

It doesnt even matter how much resistance there is. In a series circuit the voltage drop across each resistor will be directly proportional to the size of the resistor. Express your answer in terms of the variables l c and r.

To understand why think back to the series circuits described above. B at what angular frequency is the voltage amplitude across the inductor at maximum value. Voltage across r 2 ir 2 1ma x 2kw 2v.

For example if a 300 ohm resistor is attached across the terminals of a 12 volt battery then a current of 12 300 004 amperes flows through that resistor. The voltage drop across a 2 ohm resistor depends on the current flowing through it. As voltage e equals current i times resistance r if 12 amp is flowing through your 2 ohm resistor 12 times 2 1 volt.
