![]() ![]() To use it, just specify how many parallel resistors there are and the resistance value for each one. This tool was designed to help you quickly calculate the equivalent resistance of up to 6 resistors connected in parallel. Technical information, teaching suggestions, and related resources that complement this Concept Builder are provided on the Notes page. Circuit schematic for resistors connected in parallel. Learners and Instructors may also be interested in viewing the accompanying Notes page. However, the 12 different groups of questions can be printed. There is no need for an activity sheet for this Concept Builder. Users are encouraged to open the Concept Builder and explore. Use of this Concept Builder with our Task Tracker system allows teachers to track student progress. Help is provided for each difficulty level. In the circuit of Figure 1, first use the parallel resistance. This voltage level is now safe for the sensor to handle. Then, use Ohms Law to calculate the voltage drops across and currents through each part. If the voltage from the microcontroller is 5V, then the leveled-down voltage to the sensor is calculated as: V out 5 2k 2k +1k 3.33V V o u t 5 2 k 2 k + 1 k 3.33 V. Learners can repeat a difficulty level in an effort to improve their health percentage. The circuit above shows a voltage divider circuit involving a 2k and a 1k resistor. ![]() A built-in number pad makes numerical entry very easy on mobile devices by preventing the device keyboard from covering the question.Feedback is immediate and learner progress is tracked using a health bar. The analysis includes filling in a table with numerical values of battery voltage, resistance, and current at various locations. Examples of Calculating Parallel Resistance in a Parallel. So for calculating the average resistance of a series-parallel circui, we have to find. The following two problems demonstrate how to calculate equivalent resistance in a parallel circuit. R Calculations Concept Builder challenges learners to conduct an analysis of a simple circuit with one resistor ( Apprentice Difficulty Level) and of a parallel circuit with two resistors ( Master Difficulty Level) and three resistors ( Wizard Difficulty Level). There is no definite formula for series and parallel circuit combination. The equation can be rearranged to give current voltage resistance I V R.Concept Builders » Electric Circuits » Parallel-Circuits
