Simple d.c. Circuits

At the end of this week, the students should be able to:

• Calculate current using ohm’s law
• Calculate voltage using ohm’s law
• Calculate the resistance using ohm’s law

2.4.4 Calculating Current
        In this section, you will learn to determine the current values when you known the values of voltage and resistance.
       As examples, by using the following formula I = V/R . In order to get current in amperes, you must express the value of voltage in volt and the value of resistance in ohms.

2.4.5 Calculating Current
In this section, you will learn to determine the current values when you known the values of voltage and resistance. As examples, by using the following formula I = V/R . In order to get current in amperes, you must express the value of voltage in volt and the value of resistance in ohms.

2.4.6 Calculating
        In this section, you will learn to determine the resistance values when you known the values of voltage and current. As examples, by using the following formula R = V/I
        In order to get resistance by ohms, you must express the value of voltage in volts and the value of current in amperes.
