9 Introduction to Units: Team Practice HEADING PROBLEM STATEMENT ADD UNIT CONVERSTIONS AND FIGURES SET UP CALCULATION AND /OR SOLVE FOR DESIRED VARIABLE EE 1305 Name Group #/Name Date Ohm s Law relates the current flowing through a resistor to the voltage drop across the resistor and the resistance of current flow through the resistor material. Therefore, the current is directly proportional to the voltage and inversely proportional to the resistance or V = IR or I = V/R. Determine the current flowing through a resistor in units of ma if the voltage drop across the resistor is 4.98 V and the resistance is k. Show ALL units and unit conversions. Include the unit conversion V = A Equations/Unit Conv Figures/Circuits V = IR V = A Calculations 1 A = 103 ma 10 3 = 1 k The current =? INDICATE SOLUTION Solution The current =?

10 Introduction to Units: Team Practice EE 1305 Name Group #/Name Date Frequency is the number of cycles per second associated with a sinusoidal signal, and it has units of Hz (or 1/s). Convert 1.5 x 10 4 mhz (milli-hertz) to units of MHz (Mega-Hertz). Show all units and unit conversions for full credit. Equations/Unit Conv 10 3 mhz = 1 Hz 10 6 Hz = 1 MHz Figures/Circuits Calculations The frequency =? Solution Frequency =? USE A STRAIGHT EDGE FOR ALL LINES!!!

11 Introduction to Units: Team Practice EE 1305 Name Group #/Name Date Power has units of Watts (W) and is equal to Energy per unit time or Joules per second (J/s). In a circuit, power can be generated or consumed. We will talk more about this later. Since Power is equal to Voltage times Current (P = V*I), determine the power (in Watts) associated with a voltage drop of V and a current of 5.15 ma. Show all units and unit conversions for full credit. P = IV Calculations 1 A = 10 3 ma W = J/s Equations/Unit Conv V = J/C A = C/s The power =? Figures/Circuits Solution Power =? USE A STRAIGHT EDGE FOR ALL LINES!!!
