Solve the problem. Assume all numbers are approximate unless otherwise stated or the number has been determined by a definition or counting process.The current (in amperes, A) running through a resistor in an electric circuit can be calculated by dividing the voltage measured across the resistor (in volts) by the resistance of the resistor (in ohms). If the voltage measured across a resistor is 
and the resistance is 210 ohms, how much current runs through the resistor?
A. 69,000 A
B. 25 A
C. 0.88 A
D. 1.1 A
