well known problem of software development is that there is very little scientific foundation to the subject. Electrical engineers can use physics as the foundation of their activities. As a result the measures they use in their daily work‚ such as Volt and Ampere‚ correspond to well defined phenomena (electric potential‚ electric current)‚ and satisfy the rules and properties defined by theories of measurement‚ such as the representational theory [11]. The models they use‚ such as the Ohm’s law

becomes too high to measure. The applied voltage is measured across the open. 4. What is a short circuit? Name several characteristics. A short circuit is a circuit that has zero resistance. Any components in parallel with a short circuit has zero volts across it‚ and all the current goes through the short circuit. It is often referred to as a short. Characteristics of a short circuit included the resistance of the shorted component is extremely low. The current through the short-circuit current path

resistor with the handheld DMM. Remember that you should remove the resistor from the circuit to obtain an accurate reading. Connect the input of the circuit to the variable positive supply connections on the power supply. Set the DC power supply to +10 volts. Use the handheld DMM to verify the input voltage is +10 V. Measure and record each voltage listed below with the handheld DMM. Measure the current last. Have the professor verify the connections before applying power. = __9.9V__ = __1.33mA_
