a200ohm resistor has a voltage of 6v series it\'s leads.

what is the power dissipated on this resistor?

what is the current through the resistor?

Solution

Resistance R = 200 ohm

Voltage V = 6 volt

(a).the power dissipated on this resistor P = V ² / R

                                                             = 6 ² / 200

                                                            = 36 / 200

                                                            = 0.18 W

(b).the current through the resistor i = V / R

                                                    = 6 / 200

                                                    = 0.03 A
