Brand New Decade Resistance Box - Ideal Substitution for Standard Resistors - Ranges Over Four Decades - 0 to 11,110 Ohms - Eisco Labs Manufacturer model: PH1133A4 RESISTANCE || Standard four decade resistance box used to calculate resistance - Accommodates most student experimentsRANGE || Ranges from 0 - 11,110 Ohms in increments of 1 Ohm - 1% tolerance - Maximum power output of 2W - Lowest Amperage: 20mA - Highest Amperage: 700mAEASY TO USE || Resistances are easily selected by the turn of a dialNOT INCLUDED || At least 2 banana plug cords, alligator clips, a power supply, and at least 1 multi-meter are required for use but are not includedSAFE HANDLING || It is important to set the resistance high enough in order to maintain a power output that is less than 2W - Too much current could start a fire or melt part of the box - No safety fuse Description This decade resistance substitution box provides 4 decade ranges as given below and total value 0 to 11110 Ohms with a resolution of 1 Ohm. Each decade is selected using rotary switch. All resistance values are of 1% tolerance and with 0.5 watt resistors, 0.5555 watts is the theoretical maximum. At least 2 banana plug cords, alligator clips, a power supply, and at least 1 multi-meter are required for use but are not included.It is important to set the resistance high enough in order to maintain a power output that is less than 2W.Too much current could start a fire or melt part of the box.No safety fuse.Suggested experiments include Ohm's Law: Finding the Relationship Between Current and Voltage (Constant Resistance), Ohm's Law: Finding the Relationship Between Current and Resistance (Constant Voltage) and The Wheatstone Bridge: Determining the Resistance of an Unknown Resistor.Eisco Labs proudly manufactures its own products using state-of-the-art equipment, and following the highest standards of quality control. Each product is carefully designed by a team of laboratory professionals and experienced engineers with quality and durability in mind.
