3. Ohm's Law states that the potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance," R. The internal resistance of the circuit can be measured by the formula E = IR, where I is the current, in amperes (A); R = x + 6.1 ohms; x is the ohms of the resistor; and 6.1 is the internal resistance of the circuit. a) Find I if E = 1.6 volts. b) What is the domain of the function you found in part a)? c) What is the maximum value of I? d) Graph the function in part a). Is there a vertical asymptote? e) What happens to I when the resistance is very large?

Question
Transcribed Image Text:3. Ohm's Law states that the potential difference (voltage) across an ideal conductor is
proportional to the current through it. The constant of proportionality is called the
"resistance," R. The internal resistance of the circuit can be measured by the formula
E = IR, where I is the current, in amperes (A); R = x + 6.1 ohms; x is the ohms of the
resistor; and 6.1 is the internal resistance of the circuit.
a) Find I if E = 1.6 volts.
b) What is the domain of the function you found in part a)?
c) What is the maximum value of I?
d) Graph the function in part a). Is there a vertical asymptote?
e) What happens to I when the resistance is very large?
