IntoScience Electrical Circuits Aim: To investigate and construct electrical circuits and diagrams, using the online program IntoScience. Keywords: Current, Voltage, Ohms, Ohm’s Law This lesson we went onto the online program, IntoScience, to investigate electrical circuits. We completed the module “Electrical Circuits,” and learnt about Ohm’s Law and the relationship between resistance, current and voltage. These diagrams below, illustrate a series circuit and a parallel circuit, each with exactly the same components, in the same position, however the wires are positioned differently. In the series circuit, the energy has to flow through each component, increasing the resistance and reducing the amount of energy each component receives. In the parallel circuit, the current flows through each component separately, meaning that they each receive a larger amount of energy than they would if they were arranged in a series circuit. The construction of a parallel circuit also means that if one electrical component is destroyed, the others will continue to work. In this lesson, we also learnt about Ohm’s Law. This is illustrated in the triangular diagram below. Ohm’s Law describes the relationship between current, voltage and resistance and states that voltage (V) = Current (I) x Resistance (R), I = V/R and R -= V/I. Lesson Summary:
Learnt about Ohm’s Law Learnt the proper measurement for measuring resistance, ohms. Constructed series and parallel circuits and their respective diagrams.
