The emf of a cell is `Ev`, and its its internal resistance is `1Omega`. A resistance of `4Omega` is joined to battery in parallel. This is connected i

Correct option is  B) 1 A

rausch’s law states that the equivalent conductivity of an electrolyte at infinite dilution is equal to the sum of the conductances of the anions and cations. The molar conductivity of a solution...

Given: E = 12 volt, r = 10 Ω, R = 230 Ω To find: Reading shown by voltmeter (V) Formula: i. I = \(\frac{E}{R+r}\) ii. V = E – Ir Calculation: From formula (i), I = \(\frac{12}{230+10}=\frac{12}{240}=\frac{1}{20}\) A From...

Given: E = 10 V, r = 3 Ω, I = 0.5 A To find: i. Resistance of resistor (R) ii. Terminal voltage of battery (V) Formula: I = \(\frac{E}{R+r}\) Calculation: From formula, R = \(\frac{E}{I}-r\) ∴...
