Chapter 1, Problem 1P Step-by-step solution Step 1 of 4 (a) Write the expression of Ohm's law. V IR Here; V is voltage I is current R is resistance Substitute 1 kΩ for R and 5 V for V. 5 = I I = 5 mA Thus, the value of the current I is 5 mA 5 Step 2 of 4 (b) Write the expression of Ohm's law. V = IR Substitute 1 mA for I and 5 V for V. 5 = R = 5 kΩ Thus, the value of the resistance R is Step 3 of 4 (c) Write the expression of Ohm's law. V = IR Substitute 10 kΩ for R and 0.1 mA for V = = V Thus, the value of the voltage V is Step 4 of 4 (d) Write the expression of Ohm's law. V = IR Substitute 100 Ω for R and 1 V for V. = I (100) I = 10 mA Thus, the value of the current I is
