ABCD is a rhombus. DPR and CBR are straight lines. Prove that: DP.CR=DC.PR Solution: DP.CR=DC.PR Given ABCD is rhombus . DPR and CBR are straight lines.∴ AD||CR we need to Prove : DP.CR=DC.PRIn ∆ ADP and ∆ PCRWe have : ∠ APD = ∠ CPR ∠ ADP = ∠ PRC ∠ DAP = ∠ PCR … Read more
Suppose a Current I flows through a circuit as shown in the figure. The voltage across the resistance is V . The P.D. is the work done to move a charge Q from one point to another point, between which the p.d. is applied. W = QVBut, Q= I.t ∴ W = VIt Another energy … Read more

Emf: Emf is defined as work done per unit charge in taking a positive charge through the complete circuit ( the circuit outside the source (cell) and inside of the source. emf is represented by greek letter ε If W is the work done when a test charge of q0 is taken through the complete … Read more
मैने कल रात एक सपना देखा, कि मैं एक बादल था। मैं वाष्प से बना था और मुझ में पानी था। मैं पानी से बोझिल था, और बौछार करने के लिए इंतजार कर रहा था । मै अपने आपको किसी भी आकार भें ढाल सकता था । थोड़ी ही देर में मै कुत्ता बन गया … Read more
Resistance: Resistance of a conductor is the opposition offered by the conductor to the flow of current through it. Resistances are of two type fixed resistance and variable resistance. Reason of resistance: The resistance is due to collision of moving electrons while moving from negative terminal to positive terminal. In this process when electrons collide … Read more
Potential Difference:Potential difference between two terminal of a conductor is the work done while carrying unit positive charge from one terminal to the other terminal. Unit of the potential difference is volt. V = W / Qor 1 V = 1JC-1 1 Volt is equal to 1 Jouls/coulomb. and W = QVAbove equations should be … Read more
