SUMMARY

The voltage across a 60-microfarad capacitor charged by a 6mA constant current for 10 seconds can be calculated using the formula V = (1/C) ∫i dt. By integrating the current with respect to time and multiplying by 1/C, the resulting voltage is derived. It is important to note that the initial voltage across the capacitor is not specified, which may affect the final calculation. The integration yields a precise and even voltage value.

PREREQUISITES
  • Understanding of capacitor charging principles
  • Familiarity with integral calculus
  • Knowledge of electrical current measurement (mA)
  • Basic concepts of voltage and capacitance
NEXT STEPS
  • Study the integral calculus techniques for electrical applications
  • Learn about the relationship between current, voltage, and capacitance in RC circuits
  • Explore advanced capacitor charging formulas and scenarios
  • Investigate the effects of initial voltage on capacitor charging calculations
USEFUL FOR

Electrical engineers, physics students, and anyone involved in circuit design or analysis will benefit from this discussion on capacitor voltage calculations.

The question asks, to what voltage would a 60-microfarad capacitor be charged by a 6mA current lasting 10 seconds?

I used this formula, V=1/C ∫i dt
but I'm not sure how to solve the integral.
Thanks for any help

Your integral looks good. You just need to integrate the current with respect to time and multiply by 1/C.

Note the problem does not state that the initial voltage across the capacitor is zero.

If I did this correctly, I got a very nice even number - VERY even.
