Parts and what they mean

• Centre-tap transformer (केंद्र-निष्कासित ट्रांसफ़ॉर्मर) — The secondary has a tapping at its midpoint. Each diode gets only half the total secondary voltage.
• ac input (ac इनपुट) — Applied to the primary.
• End A of the secondary (द्वितीयक का सिरा A) — Connected to the p-side of D1.
• End B of the secondary (द्वितीयक का सिरा B) — Connected to the p-side of D2. Its voltage is always opposite in phase to A (relative to the centre tap).
• Centre tap (केंद्र-टैप) — The midpoint of the secondary: one output terminal.
• Diode D1 (डायोड D1) — Forward biased when A is positive with respect to the centre tap: conducts in the positive half-cycle.
• Diode D2 (डायोड D2) — Forward biased when B is positive: conducts in the other half-cycle.
• Common point X (n-sides joined) (उभयनिष्ठ बिंदु X (n-ओर जुड़े)) — The n-sides of both diodes are joined here; output is taken between X and the centre tap.
• Load resistor RL (लोड प्रतिरोधक RL) — Gets current in BOTH half-cycles, always in the same direction.
• Current through RL (RL में धारा) — From X towards the centre tap in both halves of the cycle.
• Wires (तार) — p-sides of D1, D2 to the ends A, B; n-sides joined at X.
• (b) Input to D1 at A ((b) A पर D1 को इनपुट) — Voltage of A relative to the centre tap.
• Input to D2 at B (B पर D2 को इनपुट) — Opposite in phase to A: when A is +, B is −.
• (c) Output across RL ((c) RL के पार आउटपुट) — Output in both halves of the cycle: more efficient than half-wave.
• Pulse from D1 (D1 से स्पंद) — Positive half-cycle (A positive).
• Pulse from D2 (D2 से स्पंद) — Negative half-cycle (B positive). For 50 Hz input the output pulses repeat at 100 Hz.
