RRB Junior Engineer / DMS / CMA 2019 · Question 3483 of 3719
Explanation: ∴P = cos α−μ sin α W sin α+μ cos α ( ) ⇒P = W ( 1−μ tan α tan α+μ ) ⇒P = W ∵μ = tan ϕ ( 1−tan α tan ϕ tan α+tan ϕ ) [ ] SI Unit of Electric Potential difference is Volt (V). The Electric Potential difference is also known as Voltage. Voltage is measured using Voltmeter. Electric Potential difference (V) = Work done/Charge V = Joule/Coulomb Units Physical Unit Watts Power Ohms Resistance Coulomb Charge
