During the positive half cycle of a.c., the end A is positive and the end B is negative. The diode Dis forward biased and a current l flows through R<sub>L<\/sub>. As the input voltage increases or decreases, the current l also increases or decreases and so does output voltage (=IR<sub>L<\/sub>) across the load R<sub>L<\/sub>.
