ABCD is a Rhombus. DPR and CBR are straight lines. Prove that: DP.CR=DC.PR

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.PR
In ∆ ADP and ∆ PCR
We have :
APD = CPR
ADP = PRC
DAP = PCR
∆ ADP and ∆ PCR are similar triangle .
we can write
AD/DP=CR/PR
Or AD.PR = DP.CR
DC .PR = DP.CR Proved

1.Electrical Energy Equation Class 10 Physics

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 = QV
But, Q= I.t

∴ W = VIt


Another energy equation By Ohm's Law:
V= I. R
Now, W = VIt
W = IR. It
∴ W = I2Rt

We can also write the energy equation in terms of voltage , resistance and time.
W = (V / R )2. Rt
∴ W = (V2t) / R

∴ W = Qv = VIt = I2Rt= (V2t) / R
