Download Solution PDFConcept:
- Current through a given area of a conductor is the net charge passing per unit time through the area.
- Let ΔQ be the net charge flowing across a cross-section of a conductor during the time interval Δt, then
- \(i = \frac{Δ Q}{Δ t}\) ----- (1)
- The SI unit of current is ampere.
- If one coulomb of charge crosses an area in one second, the current is one ampere.
Calculation:
Given data: Current, i = 0.6 A,
Time Δt = 10 minutes = 10 × 60 = 600 seconds
From equation (1)
⇒ i × Δt = ΔQ
⇒ ΔQ = 0.6 × 600 = 360 C
Additional Information
- If the moving charges are positive, the current is in the direction of motion.
- If the moving charges are negative, the current is opposite to the direction of motion.
