Questions & Step-by-Step Solutions

In a DC circuit, if the voltage across a 10Ω resistor is 20V, what is the current through the resistor?
  • Step 1: Identify the values given in the problem. We have a voltage (V) of 20 volts and a resistance (R) of 10 ohms.
  • Step 2: Recall Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). The formula is I = V / R.
  • Step 3: Substitute the values into the formula. Replace V with 20V and R with 10Ω: I = 20V / 10Ω.
  • Step 4: Perform the division. Calculate 20 divided by 10, which equals 2.
  • Step 5: State the result. The current (I) through the resistor is 2 amperes (A).
